I know many of us are less motivated to go the gym or wanna try to find a good workout video to help with our abdominal muscles. Here I have found a good link to a 15 minute workout to start you off. Pace yourself and add more repetitions each time. If you are still not sweating, proceed to my favorite, the plank series:
For those able to advance to the prone or side plank I have made available this link to show you correct posture. These moves can be done to strengthen your obliques, after working on your "six pack" muscles. I even like to hold a correct pushup position - the prone plank, and hold that for upto one minute, the last exhauster before stretching. ENJOY.
